WILLIAM B. lPARsmvs, lour/Daimon, NEW YORK.

LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 352,710, datedNoVernber 16, 1886.

Application filed August 5, 1886. Serial No. 210,11'5. (No model.)

To all whom it may concern.:

tion of the swivel or joint by which the twol roller-frames are connected, by which I secure ahorizontal and a 'vertical movement of one frame independently of the other. f

The invention further consists in various features and details of construction hereinafter fully set forth.

In the drawings, Figure 1 is a perspective View of my improved roller, and Fig. 2 a ver-k tical cross-section of the same.

A indicatesthe front roller, and B the rear roller, the supporting-frames C D of which are connected by a coupling or swivel-joint, E, as shown in both the figures. The lframe C, in

which the roller A isL mounted,is provided with a horizontal bar or. beam, a, and two depending arms, b b, which latter receive the j ournals or gudgeons c of the roller. end of the roller A the horizontal bar or beam a is flattened or enlarged to form a bearing plate or surface, d, and at the front side of the bar or beam a the latter is provided with an extension, c, to which the tongue or pole F is pivoted.

The frame D of the rear roller consists of arms ff, which form bearings for the journals g of the roller B,- the two arms projecting from the journal radially upward above the roller and being connected at the inner end of the roller by a cross-bar, 7L.

The coupling E consists of a block or lug, t', and a horizontal forwardly-extending plate,j, which latter is adapted to rest .and bear upon the bearing-face d of the front frame.

Rear frame, D, is connectedy or pivoted to the coupling by means of a cylindrical stem or journal, G, formed integral with and projecting horizontally from the frame D at the point Near the inner where the arms f and h are joined. Stein or journal G is prevented from moving lengthwise in the block t byv means, of a collar, k, at the rear and a nut, Z, at the front side of the block Seated in the bar a, in the center of the bearing-face d, is a bolt, H, which is prevented from turning therein, and extends upward through the horizontal plate j of the coupling, as shown in Fig. 2, the bolt also passing through the lower end of the seat spring or standard I, and securing the same in place.y

The seat spring or standard is perforated at its lower end to receive the boltv H, and the nutmplaced upon the bolt secures both against displacement. Washers will advisably be placed between the lower face of plate 7' and the bearing-face d.

It will be noticed that the bolt E, stem G, andy tongue F are all in the same line, and hence the pull upon the latter tends to keep the rollers A B in proper alignment.

rIhe rearframe, D, with the coupling may swing horizontally about the vertical bolt H, so that in turning ,less room is required than under some other constructions. l

t will also be observed that the rear roller may swing vertically upon thehorizontal stem or journal G, so asto allow the roller to vary its inclination, to follow undulations of the ground or when meeting with an obstruction.

In my prior patent,above referred to, and in other patents, provision has been made for allowing the reark rollers to tip vertically, to adjust themselves to the inequalities of the surface, and the frames of said rollers are connected to the frame of the forward roller by means of a vertical pivot, so as to allow the forward roller to swing horizontally relatively to the rear rollers, and of courseI make no broad claim to such features. My present invention, I believe, possesses material advantages o`ver these prior constructions, as it is exceedingly simple, strong, and is capable of being turned easier and in smaller space than many now in use.

Having thus described my invention, what I claim is 1. In aland-roller, the combination of the two independent frames C D, provided with rollers A B and located one in advance of the other, a single block or coupling, E, connect- IOC) ing the tWo-roll-er-frames at` or near their in-ner ends and substantially in line with the tongue, substantially as shown.

2. In combination with rollers A B, one in advance of the other, frames C D, applied to said rollers, a forwardly-extending journal or stem, G, formed upon frame D, at the inner end thereof, a vertical bolt, H, secured to frame C near its inner end, in line With stem G, and a coupling, E, comprising perforated block z', to receive stem G, and perforated plate 7', to receive bolt H, all substantially' as shown.

3. In combination with roller A, having frame C, a roller, B, a frame, D, therefor, consisting of the arms f and h, united at the inner end of the roller to form a journal, G, a coup- Ytongue or pole F, pvoted to bar a, roller B, a frame, D, therefor, provided with arms f and h, united to forni a journal, G, a coupling,

E,- consisting of block z' and plate j, both perforated, as shown, and a seat-standard having its lower end perforated and held in place by the bolt H.
